BACKGROUND: Closure of fasciotomy wounds poses a challenge, particularly in pediatric cardiac patients who are too high risk for general anesthesia and often require anticoagulant treatment. The adhesive skin closure technique enables wound closure without the need for a secondary procedure such as surgery requiring anesthesia. OBJECTIVES: This study sought to describe a treatment modality that assists in fasciotomy wound edge approximation without the need for surgery, while additionally aiding in achieving fast and aesthetic results in the aforementioned patient population. A case series of 4 pediatric patients with fasciotomy wounds is presented. MATERIALS AND METHODS: Adhesive skin closure strips (Steri-Strips, 3M, St. Paul, MN) were placed perpendicular to the cleansed wound leaving small gaps for drainage, thus achieving complete propinquity. The strips were replaced sequentially with new strips every 2 to 3 days. Digital pictures of the wounds were obtained until complete closure of the wounds was achieved. Outcome variables included wound closure success rates and complication rates including infection, bleeding, and late scar formation. RESULTS: Patient ages ranged from 2 weeks to 2 years, 9 months (mean: 10.5 months), average period of open wound prior to closure was 6.75 days (range: 5-11 days), treatment duration ranged from 15 to 26 days (mean: 21 days), and average follow-up was 4.5 months. One patient died due to their primary condition. No local infections, wound dehiscence with the treatment regimen, or any other immediate complications were encountered. There was a late complication in 1 patient who presented with a hypertrophic scar. CONCLUSIONS: Use of the adhesive skin closure method to close fasciotomy wounds in pediatric patients in which surgical procedures were nonadvisable produced favorable results.

Community-based programs are critical for locally targeted public health education and accessible service delivery. Deriving useful information from such programs is important for their own evaluation and improvement and may facilitate research collaboration with partners and experts. Here we present an interactive Web-based application designed for a community-based oral health outreach program called ElderSmile to demonstrate how data can be summarized, filtered, compared, and visualized by time and place to inform program planning, evaluation, and research. The ElderSmile TimeMap ( http://www.acsu.buffalo.edu/ approximately smetcalf/resources/timemap.html ) is an emergent product of a US National Institutes of Health-funded collaboration of knowledge sharing among multidisciplinary team members at the University at Buffalo, Columbia University, and New York University.

PURPOSE: To determine the influence of atmospheric pressure plasma (APP) treatment on the microtensile dentin bond strength of two self-etching adhesive systems after one year of water storage as well as observe the contact angle changes of dentin treated with plasma and the micromorphology of resin/dentin interfaces using SEM. MATERIALS AND METHODS: For contact angle measurements, 6 human molars were sectioned to remove the occlusal enamel surface, embedded in PMMA resin, and ground to expose a flat dentin surface. Teeth were divided into two groups: 1) argon APP treatment for 30 s, and 2) blown air (control). For the microtensile test, 28 human third molars were used and prepared similarly to contact angle measurements. Teeth were randomly divided into 4 groups (n = 7) according to two self-etching adhesives and APP treatment (with/without). After making the composite resin buildup, teeth were sectioned perpendicular to the bonded interface to obtain beam specimens. The specimens were tested after 24 h and one year of water storage until failure. Bond strength data were analyzed by three-way ANOVA and Tukey's post-hoc test (alpha = 0.05%). Three beam specimens per group that were not used in the bond strength test were prepared for interfacial SEM analysis. RESULTS: APP application decreased the contact angle, but increased the bond strength only for one adhesive tested. SEM evaluation found signs of degradation within interfacial structures following 1-year aging in water. APP increased the dentin surface energy, but the effects of APP and 1-year water storage on dentin bond strength were product dependent. CONCLUSION: APP increased the dentin surface energy. It also increased the bond strength for Scotchbond Universal, but storage for one year negated the positive effect of APP treatment.

Patients with multisutural craniosynostosis can develop anomalous venous connections between the intracranial sinuses and cutaneous venous system through enlarged emissary veins. Cranial vault remodeling in this subset of patients carries the risk of massive intraoperative blood loss and/or occlusion of collateral draining veins leading to intracranial venous hypertension and raised intracranial pressure, increasing the morbidity of cranial expansion. The authors report the use of spring-mediated expansion as a technique for cranial reconstruction in which the collateral intracranial venous drainage system can be preserved. A patient with bilateral lambdoid, sagittal, and unicoronal synostosis presented for cranial reconstruction. A tracheostomy and ventriculoperitoneal shunt were placed prior to intervention. At the time of reconstruction, a Luckenschadel skull abnormality and Chiari malformation Type I were present. A preoperative CT venogram demonstrated large collateral superficial occipital veins, small bilateral internal jugular veins, and hypoplastic jugular foramina. Collateral flow from the transverse and sigmoid sinuses through large occipital emissary veins was seen. Spring-mediated cranial vault expansion was performed with care to preserve the large collateral veins at the occipital midline. Four springs were placed at each lambdoid and the posterior and anterior sagittal sutures following 1-cm strip suturectomies. Removal of the springs was performed 2 months postoperatively. Cranial vault expansion was performed without disturbing the aberrant intracranial/extracranial venous collateral system. Estimated blood loss was 150 ml. A CT scan obtained 3 months postoperatively showed resolution of the Luckenschadel deformity and a 40% volumetric increase in the skull compared with the preoperative CT. Patients with anomalous venous drainage patterns and multisutural synostosis can undergo spring-mediated cranial vault expansion while preserving the major emissary veins draining the intracranial sinuses. Risks of blood loss, intracranial venous hypertension, and increased intracranial pressure may be decreased compared with traditional techniques of repair.

Perioperative infection is the most common and dreaded complication associated with tissue expander (TE) breast reconstruction. Historically, the expansion period was thought to be the time of greatest hazard to the implant. However, recent institutional observations suggest infectious complications occur prior to expansion. This investigation, therefore, was conducted to determine the timing of infectious complications associated with two-stage TE breast reconstructions. Following IRB approval, a retrospective review of all consecutive two-stage immediate TE breast reconstructions at a single institution from November 2007 to November 2011 was conducted. Reconstructions were then divided into two cohorts: those suffering infectious complications and those that did not. Infectious complications including minor cellulitis, major cellulitis, abscess drainage, and explantation were identified. Various operative and patient variables were evaluated in comparison. Eight hundred ninety immediate two-stage TE breast reconstructions met inclusion criteria. Patients suffering infection were older (55.4 years versus 49.3 years; p < 0.001), and more likely to have therapeutic mastectomy (94% versus 61%; p < 0.0001), the use of acellular dermal matrix (ADM; 72.5% versus 54.9%; p = 0.001), and greater initial TE fill (448.6 mL versus 404.7 mL; p = 0.0078). The average time to developing of infectious symptoms was 29.6 days (range 9-142 days), with 94.6% (n = 87) of infections prior to the start of expansion. Perioperative infections in immediate two-stage TE to implant breast reconstructions are significant and occur mostly prior to the start of expansion. Thus, challenging the conventional wisdom that instrumentation during expander filling as the primary cause of implant infections. Possible etiologic factors include greater age, therapeutic mastectomy versus prophylactic mastectomy, larger initial TE fill, and the use of ADM.

BACKGROUND: Trichloroacetic acid is routinely used by gynecologists to treat anogenital diseases, and accidental exposure to the health care providers may result in serious burns. This case serves to raise awareness of accidental exposure of trichloroacetic acid and describes preventive, first aid, and treatment recommendations that may limit the incidence and severity of burn injury among gynecologists. CASE: A 32-year-old female gynecologist incurred a deep second-degree, 12x14-cm, work-related chemical burn by unintentionally spilling a container of approximately 20 mL of 80% trichloroacetic acid onto her right thigh during an outpatient procedure. First aid included removal of her soaked clothing, 5 minutes of soap and cold water irrigation, and liberal placement of petroleum-based ointment onto the injury site. Treatment consisted of topical silver sulfadiazine cream twice a day, coverage with silver-impregnated silicone foam dressing, and a circumferential soft bandage to minimize sheer forces along the wound. A 9-month follow-up demonstrated a well-healed, mildly hypopigmented, aesthetically favorable wound with return of sensation. CONCLUSION: Accidental trichloroacetic acid burns are a potential hazard in a gynecology office. Health care workers should be familiar with prevention, first aid, and appropriate treatment that often can result in acceptable long-term outcomes.

Recent technical and scientific advances in fat grafting procedures and concepts have improved predictability of fat grafting. Large-volume fat injection is gaining much attention as an attracting procedure for body contouring and reconstruction, but an increasing number of complications also has been recognized over the world. In this article, typical complications after fat grafting are described, as well as an explanation of how and why they occur, and how surgeons can avoid and treat complications.

The controversy over fat grafting to the breasts has now been settled. In 2009, the American Society of Plastic Surgeons Fat Graft Task Force stated that "Fat grafting may be considered for breast augmentation and correction of defects associated with medical conditions and previous breast surgeries; however, results are dependent on technique and surgeon expertise." This article discusses the history, indications, planning, complications, and present technique of fat grafting to the breast using the Coleman technique.
